There are four seasons in a year, but the danger of a fifth season lurks everywhere. The ground is unstable: volcanoes, geysers, and earthquakes loom, and a massive, planet-killing event waits just around the corner to usher in an unending winter in which humanity must struggle to survive. Orogenes have the skill to mediate the seismic – or cause them, manipulating geological energy, and so they are hated, feared, and enslaved, as the economy of the world rides on their shoulders. This is the book I’ve been waiting for from Jemisin: grapples with slavery, tropes, gender, class, empire, and much more.
